MasterCard DNS Error Went Unnoticed for Years as Magecart Infections Surge to 11,000 Unique Domains

A recent report highlights that a DNS error at MasterCard went unnoticed for several years, raising concerns about cybersecurity vulnerabilities. The issue was initially reported by Krebs on Security and has since been reiterated by multiple sources. This revelation comes amid a broader context of increasing cybersecurity threats, particularly with the volume of Magecart e-skimmer infections surging to nearly 11,000 unique e-commerce domains, a threefold increase from 2023. This spike is attributed to the CosmicSting vulnerability (CVE-2024-34102) and the utilization of readily available e-skimmer tools.
